- spore measurements (length/width) (in micrometers) I tried to include the one of the largest and smallest spores I could find along with the majority of the same sized spores that I found. Measured with an 100x oil immersion objective.

I did look it up the prince (agaricus augustus) in my guide it does match up with the characteristics of free gills, brownish colored gills, the scales and color of the cap, the chocolate brown spores, but the spore size is a little smaller ( 7.5-10 X 5-6) microns.. maybe because it was a younger specimen. The stipe was smooth which doesn’t match up perfectly. However the spore size for the princess argaric is (6.5-7.5 × 4-5 microns) and sometimes has a smoother stipe.

I tried my best to with all of the specimens in my collection, but with practically everyone I became very congested and stuffed up when working with them. For this one I could not find a distint odor.
